Java Language Specification
Java SE 12 Edition

The Java Language Specification, Java SE 12 Edition, was the official, authoritative specification of the Java programming language. It was published in February 2019 and followed the Java SE 11 Edition of the JLS.

It specifies the Java programming language as implemented in Java SE 12.

This Java SE 12 Edition goes beyond the Java SE 11 Edition of the JLS by specifying the following feature:

  • switch-expressions (but only as a preview feature)

This language change was introduced in Java SE 12 in 2019.
